Exhaust Fan Vs Kitchen Chimney – Which is Better?

A kitchen chimney (Kitchen Hood) and an exhaust fan are the most commonly used appliances for cleaning the air in the kitchen. Even if they are used for the same basic purpose, these two units are very different and making a choice between the two has always been a major challenge to many homeowners.

Since we don’t want you to make the wrong decision when choosing the most suitable appliance for your kitchen, we have compiled a detailed guide on how kitchen chimneys and exhaust fans work.

Kitchen Chimney or Kitchen Hood

In terms of performance, a kitchen hood is the best.  A kitchen chimney can be either ductless or ducted.  As compared to an exhaust fan, a ductless chimney performs the functions of 8-exhaust fan while a ducted chimney is equal to 15 exhaust fans.  This means that kitchen chimneys are highly effective in removal of oil particles, grease and smoke from your kitchen. But, they are very expensive.

Just like exhaust fans, some chimneys are able to replace polluted air with clean air. When preparing spicy foods, grease and oil particles may settle on the cabinets, shelves or the wall which gives them an ugly look. A kitchen chimney ensures that smoke, grease and oily particles do not settle on the walls, shelves or your kitchen cabinets which means that your kitchen will always have a nice look.
